Did you click that big orange button that said “Transmit my return now?” If you did that, you cannot do anything to fix it yet. You have to wait for the email that tells you if your return was accepted or rejected.
You cannot change or add anything on the return that you just e-filed, nor can you stop it. It is too late, just like when you put an envelope in a US mailbox on the corner. The IRS does not allow you to take it back.
If you left out a W-2, a 1099G, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.” The changes will go nowhere.
Now you have to wait until the IRS either rejects or accepts your return. If your return is rejected, you will be able to go into your account and make the necessary changes to your tax return and re-submit your return.
If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund. THEN you can prepare an amended tax return and e-file or mail it in. You have to be able to work from that return exactly the way it was when it was e-filed originally. You will need to use a form called a 1040X.
Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself. Sit tight and wait until you see what the IRS does with the return you just e-filed
Not sure what you did when you filed or what income information you used (pay stubs?) but going forward----never use pay stubs to prepare a tax return. They will not match the W-2's that you get from the employers. Employers have until January 31 to issue W-2's and you need to wait for all of them. Every W-2 for a specific tax year has to go on the same tax return.
And...you have two states involved. You lived and worked in Maryland for some part of 2024 so you probably need to file a part-year MD return. Texas has no state income tax, so there is nothing for you to prepare for that state.
When the IRS finishes processing the return you filed, post back here for further help if you need it in order to amend the return and enter your W-2's correctly. The form you need to amend will not be available until the middle of February.
Since you have already submitted your tax return, wait until you receive an email informing you that it is accepted or rejected. Don't make any changes while your tax return is pending.
If your tax return is rejected, you may sign in to TurboTax and add your W-2 along with fixing the rejection. If your tax return is accepted, once it’s processed, you can file an amendment through TurboTax using Form 1040-X. adding your income.
